fo all w/iom `it may concern:

le it known that I, VWatan-2N A. CHASE, a citizen ot the llnited States,residing.;- at Dorchester, in the county oit' Sutl'olk and State otittassaehusetts, have in\f'ented ,new and use'tut improvements inRefrigerators, ot whieh the followingF is a speeitieation.

My `present invention relates to i1n`prove ments in refrigerators orcooling apparatus tor animal and vegetable matters o t various kinda.and it has tot' itis object primarily to provide an improved apparatusot this Character which embodies ice containingr tanks tor prtalucintnga. flow of refrigerator air through a provision ehamber such as adaptved to'receive meats, vegetables and provisions of various kinds, inconnection with a collecting' tank or tanks, the latter being arrangedat the bottom ot' the re frigerator and adapted to receive the cooleddrip water :from the melting ice in theiee tanks.7 the waste productsoi' the ice tanks being thereby t'urtlier utilized .before they paasoll" through the waate pipi.

Another object et theinvention is to pro vide Colleetinn' tanks whichextend longitudinallyv and in substantially parallel rela-- tion betweenthe ice tanks and across the bottom ot the provision chamber, theseyeollettingr tanks serving notouly to refrigerate the provisions in theprovision chamber, but also forming; spaces between them adapted toreceive milk bottles', cans and other articles which should hemaintained at a com paratively low and constant temperature, thecollecting;v lanka receivingthe salted drip water t'rom the ieeI tanks;and thereby conrstitnt'imgr brine receiving tanks.

'further object, ot the in\.'enti n is to provide improved meany tormountingr the brine receiving or eolici-ting tanks wherebyv any numberthez'not' may be removed or replaced in order to accommodate a greateror less number of bottlei; or cans in the bottoni ot' the refrigerator,suitable devices loe-- iup; provided for coupling` the (,'olleetinpglankal to" the-ice tanks in order that they may receive 'the salted dripwater l'rorn the latter and utilize this refrigerated drip wateflieloleit esehpes to the waste pipe.

ln the'aeconipanving drawing: Figure 1 represents a longitudinalvertical section of a refrigerator' constructed in accordance with mypresent invention; Fig. 2 represents a horizontal section taken on theline @W2 ot Fig. i; Fig. 25 represents a transverse vertical section ot"the refrigerator; Fig. It is a perspective view ot the ice tanks and thecollecting tanks, these tanks being` shown removed from therefrigerator. Fig. 5 is: a detail sectional view showingr a elosing eapapplied to one ol the upright iee tanks.

Similar parts are dersigg'nated by the saine reference ehararters in theseveral views.

Refrigerators or coolini?y apparatus eonst'ructed in aeeordanee with mypresent invention may be made in various sizes and modified so as 4to he:ulapted for use either ip the household, in stores or in refrigeratorcars.` ln the present instant-o l have shown one embodiment ot myinvention which dise closes the same as applied to an ordinary`stationary refrigerator, the apparatus eomprisintg tgeneiuillyl an outerreceptacle or easing l which is preferably formed with double wallshaving the space between them titled with saw-dust or other heatinsulating material in order that the conduetivitv of heat li'roni theexterior to the interior ot the refrigerator is minimized. Mounted'within the receptacle or casini: and at the opposite ends thereof are apair of vertieally a1- rane'ed tanks 2 and 3 which may be coinposed otgalvanized iron or other appro priate material, and these tanks areadapted to contain salt and ire. These tanks are preferably arranged inparallel vertieal planes as shown, they upper ends ot' the two tanksbeing open 1nd registering;` with eorreslnionding openine'k /tand 5t'ormed in the top ot' the refrigerator, and these openings are normallyclosed by suitably hinged covers or doens.l t3 and 7 through which theice and salt may be introduced into the respective tanks. The bottom ofeach tank is provided with an ice support 8 or 9, these sup ports beingpreferably composed ot slats or racksl which permit the salt: waterdripping,I l'roin the meltingl iee to pass from the tank. 'theaevertically extending satt and ice tanks at the opposite ends ol' theret'rigerator iueloae two sides ot' a provision chamber, the walls ofthe tanksl nervin?y as the two end walls of such chamber, and the icetanks form in effect air circilating lines. ln order to insure a propercirculation of the refrigerated air -from the ice tanks into theprovision chamber and then back into the ice tanks, the proXimate wallsof the latter are provided with rows of upper and lower openings lt and16, the refrigerated air dcscending to the bottom of the ice tankspouring out through the opening linto the provision chamber, and as thisrefrigerated air takes up heat `from the provisions within said chamber,it will rise and re-enter the upper portions of the ice tanks throughthe openings 15.

Extending horizontally beneath the provision chamber and between thesalt and ice tanks are a set of collecting tanks 10 which are adapted toreceive and contain the brine. Any suitable number of these collectingtanks may be employed. For instancein those cases where it is desirableto provide a relatively large storage space below the provision chamber,one or more of these collecting tanks may be used. In the presentinstance a series of three collecting tanks l0 are shown, these tanksextending horizontally and in parallel relation beneath the provisionchamber and forming between them spaces ll adapted for the reception ofmilk bottles, cans and other articles which .it is desirable ornecessary to maintain ata relatively low temperature. rIhese collectingtanks are suitably connected at theii opposite ends to the respectivesalt and ice tanks and have communication therewith in order that thesalty drip water from the melting ice in these tanks may be received bythe collecting tanks, the drip water thus flowing into these tanksserving to provide a constant supply of lbrine solution at a lowteinperature. The brine solution in the collectingtanks is maintained ata constant level by means of a waste pipe l2 which extends upwardlythrough the bottom of the refrigerator and has its upper end opening atthe level of the brine Solution.

' In some cases, such as in the transportation of milk cans in largequantities, it may be desirable to remove some of these collecting tanksso as to provide addition-al space available for the storage of suchcans, a single collecting tank in that instance being sulticient. Inorder to provide-for such removal of certain of the collecting tanks,these tanks are removably fitted into the 'space beneath the storagechamber, suitable fluid-tight vconnections being provided between theopposite ends of the respective collecting' tanks and the ice tanks, andsuitable devices being' used to cut ott suoli connections after theremoval of the corresponding collecting tanks.

'In the present instance, the opposite ends of each collecting tank areclosed by end walls, and to these end walls are fitted nipples 17 whichare adapted tobe brought into alinement with a corresponding pair ofexternally threaded nipples 18 arranged on the inner walls of the icetanks 2 and 3,

and the necessary liquid-tight joint is provided by means of the sleevesor collars 19.,

When one 0r more of the collecting tanks are removed, caps Q0 may befitted 0n the nipples of the ice tank to prevent the escape of theliquid therefrom. The detachable connecting devices between the ice andcollecting tanks are shown, however, in the present instance as merelyone embodiment of the invention and it will be understood thatconnecting devices' of any suitable l'ind may be employed. In order topermit-' liess t the provision chamber and to the storage spaces in thebottom thereof between the collecting tanks, a suitably located door 14may be provided in one of the Walls ofthe refrigerator between the twosalt and ice tanks.

A refrigerator or cooling` apparatus constructed in accordance with myinvention is comparatively simple in construction, and as the ice isused initially to cool the provisions or other articles contained in theupper provision' chamber, whilethe refrigerated water dripping from themelting ice is utilized in maintaining the collecting; tanks at a verylow temperature, the v refrigerator obviously utilizes the iceto thegreatest advantage, and the construction of the tanks is such that theymay be 'radily 10C adapted for use in connection with refrigerators orcooling apparatus of various kinds.

I claim as my invention:-`
